STORAGE BATTERY.

1911. Serial No. 643,281.

To all 'whom it'may concern:

Be it known thatI, Jol-IN L. SMITH, a

citizen'of the United States of America, re-

sidin l.'1t:-\D'etroit, in thecounty ot' lVayne and tate`of Michigan, have invented certain new anduiseful Improvements in Stor-.

age Batteries, of `which the following is a specification, reference being..4 had therein to the .accompanying dra-wings.

This invent-ion relates to storage batteries and to an arrangement-of the elements of the plates .thereof wherebya very large area'of wetted plate surface is obtained inV small space and whereby a cell 'may be built 1-5 .up of any preferred capacity of inter` changeableelements 4that are readily assembled. i .4

'- T The, inveiition 1cen\isttsn inI the matters hereinafterse -\forth, and more particularly pointed out in the appended claims.-

n In the drawings, Figure 1 is a view inl perspective of an assembled cell thataem bodies features of the invention; lFig. 2 is aview in longitudinal section theretl'n'ough,I

parts being exa gerated in thickness in order to give a cv ear view; Figs?, isa view in section on line 3 3 of Fig. 2 with parts broken away; and Fight is a view in detail of one of the couples of the cell.

As herein shown a neutral supportingl f,sheet 1 is supported ina spacing frame. 2 of suitable material such as soft rubber, or other elastic` non-conducting material.. A honeycombed'or perforated positive plate A3 whose openings are 'filled with any preferred form of active-a,f,gent-, such 'as red lead or .the like is secured in parallel spaced' relation to onejface of the supporting sheet 1, preferably by fusing the margins thereto at.' intervals as indicated at 4, or in any other suitable manner insuring good elec-4 trical connect-ion between thel 'parts'andrigid support-to die plate, while at the same time leaving both sides of the plate or grid i5 free to be wetted by battery tluid when immersed tlgggtinl A perforated shield 5 o'f hard or thel'like is bpnnd against. the outer 'faeeirif the plate 3 as by rubber bands 6. the latter'also securing an' inner-separa- 33 (m17 ofsimilar material.l These plates act as retainers to aid in hphlingjthe active ma- .terialin'llw pockets of the grids'. On the' other side of. the .supporting lsheet l isa negative. plate R of proper material secured .in spaced relation to the snpportin;,r sheet l .in the samt-. manneras the positive plate 3 and liners or shields 9 and 10 -similar-fito those of the-positive gridare held in position by clamping bands 14]. Because of the spacedrelation of the grids from the supl 6\ 'porting sheet l, both faces' ofthe grids. or

plates'are exposed to or wetted by the battery Huid.

The spacing frame 2 is preterablyof soft rubber and embraces the lateral margins of the sheet l, the upper inturned end portions- 13 extending partially across tht` uppermargin.' An interval 'is left. between the lower margin of the sheet' 1, and the lower mem-` ber of the frame 2. One of@ the side faces -76 .of the frame 2 is provided 'with a tongue or rib 14 adapted to mate with arid enter a correspond-ng.grooverl- :in the face of a com panion -frame,;'or'is otherwise designed to form a. tightjoint therewith. A pairof end sheets 16 and 17 are also provided. Oner of these hason its inner face a positive grid 18 and liners 19 similar to those of the in termedi'ate platesythe other sheet 17 supportsa plate 2O similar to the negative ele- 80 ments of he ,intermediate sheets. Each end sheet is c osed in a spacing member 21 'ofI material similar to'that used in the 'spacing frame 2. Qne o f the' members has' a rib 22 adapted to enter the groove of an intermediate adjacent frame 2 or other provision' 'for making a tight joint therewith, and

closed by an outer wall 23 adapted to forni the ,end wall of an assembled'cell. The other end member is channeled to receive' 90 the ribs of the adjacent intermediate traine. Outer platesA 24 of4 suitable material reinforce the walls 23. .The intermediate 'seentions und the en'd plates are secured in assembled relation by suitable means, as, for 95 example, clamplng strips 25 whose inturned ends enter suitablerecesses or openings in the reinforcements 24. The supporting sheet "l is ot lsuch material that it isfnot efl'ect'cd by lliiefm't-ion of thebattery iluid 100 upon the nascent.. imiterial in the grids.-

(')ne font'ure of this construction is the a'rrangeinknt wherein' both the inner and outer surface ot' hothlthe positive and'. negative chum-nts of each couple are wetted by the batti-ry. fluid while :it the snmetime they are sustained in proper relation by the support so that they cannot. he 'dislodged 0r displaced.
